Automatic visual correction for computer screen

Abstract

An automatic visual correction system allows different users to utilize different work stations and automatically adjusts the appearance of the indicia on the computer screen of the work station so as to make the same most comfortable for the particular user. This is accomplished by storing in memory various characteristics of the appearance of the indicia on the screen such as size, focus, contrast, brightness, color (of both the indicia and the screen) and other features for each user. Each user will have preselected each of these features and once the features are selected, the same will be stored along with information identifying the user. It may also be possible to store information relating to the user's eyeglass or contact lens prescription thereby allowing the computer to automatically make adjustments for such things as focus, size, astigmatisms and the like. In use, the user merely needs to identify himself, the computer will look up the adjustments that need to be made and the computer screen will automatically be adjusted for the particular user. Alternatively, the information for a particular user could be stored on a disk or other transportable media which could then be plugged into a computer work station when desired and the adjustments on the screen would be automatically made.
